Description
Verfahren zur Darstellung eines quaternären Aminoessigsäureamidderi-vates. Es wurde gefunden, dass man durch Um setzung von Chloracetyl-N-methylanilid, her stellbar aus Mythylanilin und Chloracetyl- chlorid,
mit Dimetbylamin zum Dimethyl- aminoessigsäure -N- methylanilid und durch Behandlung des letzteren mit Stearylbromid zu der entsprechenden quaternären Ammo- niumverbindung gelangen kann. Die neue Verbindung, in festem Zustand eine salben bis wachsartige Masse von heller Farbe, löst sich sehr' leicht in Wasser und weist stark ausgeprägte, kapillaraktive Eigenschaften auf.
Sie soll Verwendung finden als Weich- machungsmittel, Abziehmittel für Kaphthol- AS- und Küpenfärbungen und als Mittel zum Verbessern der Wasserechtheit von direkt gefärbter nativer und umgefällter Zellulose.
Beispiel: <I>.</I> Zu 1 kg wässriger Dimethylaminlösung von 20,4 % werden 300 g Chloracetyl-N-me- thylanilid, hergestellt aus Methylanilin und Chloracetylohlorid, zutröpfen gelassen. An- fänglich erwärmt sich das Reaktionsgemisch kaum, erst wenn alles zugegeben ist, tritt eine Temperaturerhöhung auf 40 - 45 ein. Das Reaktionsgemisch wird im Laufe von 3 - 4 Stunden auf 80 - 90 erwärmt und weitere 20 Stunden bei dieser Temperatur gerührt.
Das Endprodukt reagiert noch pbe- nolphthaleinalkalisch und soll in Säuren klar löslich sein. Man giesst in 500 cm3 Wasser und trennt das abgeschiedene Öl ab. Hierauf gibt man zum Dimethylaminoessigsäure-N- methylanilid 1 Liter Wasser und stellt mit Salzsäure kongosauer. Die stark schäumende Lösung wird mit Äther von geringen Mengen an Nebenprodukten befreit, die wässrige Lö sung mit Soda alkalisch gestellt, das End produkt von der wässrigen Schicht abgetrennt, getrocknet und im Vakuum destilliert.
38,4 g Dimethylaminoessigsäure-N-me- thylanilid werden mit 67 g Stearylbromid zusammengegeben und 3-4 Stunden auf 130-140 C erwärmt. Das Produkt ist dann vollständig und klar wasserlöslich. Man erhält die neue Verbindung als salben- bis wachs artige Masse, die sich sehr leicht in Wasser löst und stark ausgeprägte, kapillaraktive Eigenschaften aufweist. Die neue Verbindung soll Verwendung finden als Weichmachungs- mittel, Abziehmittel für Naphthol -AS- und Küpenfärbungen und als Mittel zum Verbes sern der Wasserechtheit von direkt gefärbter nativer und umgefällter Zellulose.
Process for the preparation of a quaternary aminoacetic acid amide derivative. It was found that by converting chloroacetyl-N-methylanilide, which can be produced from mythylaniline and chloroacetyl chloride,
with dimethylamine to dimethylaminoacetic acid -N-methylanilide and treatment of the latter with stearyl bromide to the corresponding quaternary ammonium compound. The new compound, in the solid state an ointment to waxy mass of light color, dissolves very easily in water and has strong, capillary-active properties.
It is said to be used as a plasticizer, a stripping agent for kaphthol, AS and vat dyeing and as an agent for improving the water fastness of directly dyed native and reprecipitated cellulose.
Example: <I>. </I> 300 g of chloroacetyl-N-methyl anilide, prepared from methyl aniline and chloroacetylochloride, are added dropwise to 1 kg of aqueous dimethylamine solution of 20.4%. Initially, the reaction mixture barely heats up, only when everything has been added does the temperature rise to 40-45. The reaction mixture is heated to 80-90 in the course of 3-4 hours and stirred at this temperature for a further 20 hours.
The end product still has an alkaline reaction to phenolphthalein and should be clearly soluble in acids. It is poured into 500 cm3 of water and the separated oil is separated off. Then add 1 liter of water to the dimethylaminoacetic acid-N-methylanilide and make Congo acidic with hydrochloric acid. The strongly foaming solution is freed from small amounts of by-products with ether, the aqueous solution is made alkaline with soda, the end product is separated off from the aqueous layer, dried and distilled in vacuo.
38.4 g of dimethylaminoacetic acid-N-methylanilide are combined with 67 g of stearyl bromide and heated to 130-140 ° C. for 3-4 hours. The product is then completely and clearly soluble in water. The new compound is obtained as an ointment-like to wax-like mass which dissolves very easily in water and has strong, capillary-active properties. The new compound is to be used as a plasticizer, a stripping agent for naphthol -AS and vat dyeing and as a means to improve the waterfastness of directly dyed native and reprecipitated cellulose.
